+# Publishes the pure-Python nvsubquadratic wheel + sdist to PyPI on a
+# `vX.Y.Z` tag push (or manual dispatch with an existing tag).
+#
+# Routing:
+#   - prerelease tags containing "rc" (e.g. v0.1.0rc1) -> TestPyPI
+#   - final tags (e.g. v0.1.0)                         -> PyPI
+#
+# Auth is OIDC "trusted publisher" — no API token secret. One-time setup
+# required before the first run:
+#   1. On pypi.org and test.pypi.org, add a trusted publisher for this repo
+#      pointing at workflow `release.yml` and the matching environment below.
+#   2. Create GitHub environments named `pypi` and `testpypi`
+#      (Settings -> Environments).
+# The package version is read from the VERSION file; the build job fails fast
+# if the tag does not match it, so bump VERSION before tagging.
